Refrigerant Dryers
BURAN DC 0020 AB - DC 0850 AB
PRODUCT DESCRIPTION The compressed air is being fed into the dryer and being pre-cooled in the air-to-air heat exchanger by the outgoing cold compressed air.The pre-cooled air then passes through the refrigerant-to-air heat exchanger where it is being further cooled down to the required pressure dew point. The moisture in the compressed air condenses out and gathers and discharges automatically. Finally, the cold discharged air is being reheated by the incoming compressed air. This saves energy and prevents any moisture forming beyond the dryer in the compressed air system. The cooling capacity of the refrigeration cycle is being controlled by a hot gas bypass which assures the dryer functionabilty for partial loads, too.

PRODUCT SPECIFICATIONS Features:
Benefits:
Intelligent over-all concept
Type range, filter performance data, integrated monitoring functions as well as automatic condensate drain adapted for the use in central compressed air applications
Integrated pre-and afterfilter with condensate drain
Pre filter, type V, for protection of the compressed air dryer against contaminations; Afterfilter UltraPleat® M for the removal of oil aerosols and particles with high retention effiency and very low differential pressure; Safe compliance with the compressed air quality at low energy costs.
Validated performance data acc. to ISO 12500-1 and ISO 12500-3 for the integrated pre-and afterfilter
Reliable achievement of the compressed air quality according to ISO 8573-1
Compact and space-saving design with robust steel housing
Little space required at the installation site, no additional piping for the installation of pre-and afterfilter required, low storage space requirements and low transport costs
Electronic level-controlled condensate drain UFM-D at the heat exchanger
No expensive pressure drops, condensate discharge depending on the amount of condensate
Electronic controller with dewpoint indicator, operating time counter, alarm display, service display and operating display for compressed air dryer and fan; potential-free error message
Reliable monitoring of the operating condition and timely display of necessary maintenance work; Remote monitoring via potential-free error message possible
High load capacity up to pressure dew point of + 20°C
In case of overload the refrigerant compressed air dryer switches off only at a pressure dewpoint upper than +20°C
Aluminium heat exchanger
No corrosion within the heat exchanger by contact with moist compressed air; good heat transfer properties combined with low weight
